Description

Method of manufacturing a teaching fabric using hemp fiber.

The present invention relates to a method of manufacturing a teaching fabric using hemp fibers, in particular, hemp fibers, and the ramp is weaving the teaching fabric using artificial fibers to increase the hygroscopicity and flexibility, and the appearance of the fabric such as touch and shape stability It relates to a method of manufacturing a teaching fabric using hemp fibers to improve the added value of hemp fibers.

In general, hemp fiber, a natural fiber, has a trend of increasing production in recent years as a material for living and industrial use. These hemp fibers are composed of various materials such as cellulose, hemicellulose, pectin, lignin, and wax. Rain is known to have a great influence on the structure and properties of hemp fibers.

In recent years, the trend of increasing interest in natural fibers, hemp fiber has been spotlighted as a material for the summer because of excellent hygroscopicity, dyeing, heat resistance, high thermal conductivity, absorption and drying fast, but the strength is low and the elastic recovery rate Because of low and poor wrinkle recovery, the utilization rate of clothing material is low.

The resin processing method and the blending method of artificial fibers have been developed in order to improve the spindle performance, which is a drawback of such hemp fibers, and to increase the utilization rate of hemp fibers as a garment material.

However, the method of improving the spindle property by the resin processing method significantly decreases the strength during processing, and the added resin becomes poor in touch and drape. In the case of the blending method, dyeing or post-treatment is performed due to the difference in properties from other fibers. There was a problem that makes processing difficult.

The present invention was invented to compensate for the above disadvantages of hemp fiber, by making a hemp fiber as a weft yarn and inclined man-made fiber to produce a teaching fabric, excellent in elongation and wrinkle recovery, low cost and the appearance of the fabric The purpose of the present invention is to provide a method of manufacturing a teaching fabric using hemp fibers to improve the added value of hemp fibers.

The present invention for achieving the above object,

The artificial fiber is inclined, the hemp fiber is in weft and the density of the fiber is 50-55 × 50-45, the tissue is 1/1 plain weave, and the thickness is 0.4-0.6 mm. The ratio is 60:40, the ramp is made of rayon 40/2, and the weft is made of 44L of linen to prepare a teaching fabric.

According to a preferred embodiment of the present invention, a modal 40/2 may be used as the ramp of the teaching material, and Lamy 1/36 or RF 20S or CF 20S may be used as the weft yarn.

The teaching fabric according to the present invention can increase the hygroscopicity and flexibility, improve the appearance of the fabric such as touch and shape stability, and can improve the dyeing property by changing the physical properties to increase the added value of hemp fibers.

Hereinafter, the preferred embodiment of the present invention will be described in detail.

The teaching fabric according to the present invention uses artificial fibers such as ramp rayon, polyester, modal fibers, weft yarn ramie, linen, linen, R / F (Rayon / Flax) and Weave fibers using hemp fibers such as C / F (Cotton / Flax). Weaving is carried out so that the density of a fiber may be 50-55 * 55-60, and a structure is woven into 1/1 flat fabric. Weaving is to be 0.4 ~ 0.6㎜ thick, and the ratio of artificial fiber and hemp fiber is 60:40. In addition, a ramp uses rayon 40/2 or modal 40/2, and the weft yarn is made of linen 44L or ramie 1/36 or RF 20S or CF 20S.

In order to test the characteristics of the woven man-made fibers, as shown in Table 1, using a ramp rayon and using a weft yarn Lamy 1, using a ramp rayon and a liner as weft yarn 2 and using a ramp rayon 3 using R / F as the weft yarn, 4 using C / F as the weft yarn, 4 using Ram as the weft yarn, and 5 using Lamy as the weft yarn, 6, using linen as weft yarn, 7 using R / F as weft yarn, 7 using R / F as weft yarn, 8 using C / F as weft yarn, 8 Use Ramy as a weft yarn, 9, use ramp modal, use linen as weft yarn 10, and use ramp modal It is assumed that the use of R / F as the weft is 11, and the use of the ramp modal and the use of C / F as the weft is 12.

Number of each woven fabric for the characteristic test Weft ＼ warp Rayon Polyester Modal ramie One 5 9 Linen 2 6 10 R / F 3 7 11 C / F 4 8 12

In order to measure the drape property of the fabric according to the present invention, that is, the natural curve which is the outline curve of the appearance characteristics of the garment, the test piece was placed on the support of the drape test apparatus according to KS K 0815 and left for 1 minute. Project the specimen to the photosensitive paper and calculate the drape coefficient as follows using the area of the projected part.

Drape Coefficient = {(Projected Area-Area of Support) / (Area of Sample-Area of Support)} × 100

As a result, the drape property of each test piece is as Table 2 below. Here, the drape property of each test piece is judged based on 100% of hemp fibers. Larger drape coefficients mean stiff fabrics and smaller ones mean flexible fabrics.

Drape coefficient of each specimen standard One 2 3 4 5 6 7 8 9 10 11 12 Coefficient 1.204 0.412 0.494 0.274 0.407 0.759 0.667 0.584 0.751 0.474 0.531 0.287 0.402

As shown in Table 2, the drape of the woven fabrics woven according to the present invention was improved by about 40% to 80% as compared to 100% of hemp fiber. In particular, in the case of fabrics using ramp rayon or modal, the drape property is significantly increased. The drape property of the material used as the weft R / F was the best, and the drape property of the material using linen or lamination was low, but the drape property was improved compared to 100% of the hemp fiber. Therefore, the teaching fabric according to the present invention exhibited the best characteristics for garments due to reduced ductility.

In addition, in order to determine the wrinkles of the fabric was also tested the spindle. The spindle degree is measured using the Monsanto type spindle tester. The spindle degree is calculated as follows from the obtained opening degree.

Spindle degree = (θ / 180) × 100

Where θ = open angle,

As a result, the spindle degree of each test piece is as Table 3 below. Here too, judging the spindle degree of each specimen on the basis of 100% hemp fiber. The greater the degree of spindle, the more wrinkled the water and less wrinkles means fabric.

Spindle weight of each test piece standard One 2 3 4 5 6 7 8 9 10 11 12 slope 43.3 61.65 75.50 76.95 70.55 66.65 73.05 79.65 68.85 58.00 72.45 75.80 67.75 Weft 29.4 33.30 32.30 66.35 49.70 39.70 36.60 49.95 44.40 39.70 34.15 66.90 49.15

As shown in Table 3, the spindle degree of the woven fabric woven in accordance with the present invention was increased overall compared to 100% hemp fiber. The difference according to the all directions of the inclined direction and the weft direction shows that both the degree of fugitiveness in the inclined direction is greater than that in the weft direction.

In order to evaluate the condition of the teaching materials according to the present invention, six characteristics of compression, bending, surface, diagnostic, tensile, thickness, and weight were measured at standard conditions, and bending was considered anisotropy. Shear and surface characteristics were measured by the KES-FB system measured by the direction of warp and weft. On the basis of these values, the sensory evaluation value of each test piece was calculated by calculating KN-201-LDY, which is a formula for calculating the hand value of the thin female fabric.

The main sensory evaluation value of the teaching fabric according to the present invention is the feeling related to the bendability, and the fabric woven with the high density of the fabric and the elastic yarn is irrelevant regardless of the Koshi, the fabric elasticity or not, which conveys this feeling strongly. Hari means stiff spread without draping, Shari that feels crisp and rough on the fabric surface, Fukurami that feels bulky, rich and nice. Kishimi and Shinyaki, which is soft, supple and smooth, are summarized in six terms. The larger the number, the greater the intensity of each fetus.

Here, the sensory evaluation values of the notices expressed by combining the resilience, elasticity, and flexibility felt when the fabric is held by hand are shown in Table 4. As shown in Table 4, it can be seen that by showing a value less than 100% hemp fiber is less stiff than a fabric woven with only 100% hemp fiber.

In addition, as a result of measuring the Fukurami value of each test piece, no significant difference was observed as compared to 100% hemp fiber. This means that each specimen retains the unique feel of the hemp fibers. Similarly, the shari value was measured, indicating that the fibrous friction of the hemp fiber was not damaged.

In addition, as a result of measuring Kishimi, which is a sound felt when the clothes rub, it was measured that the sounds and feelings of the test samples of 1 to 4 and 9 to 12 of the test pieces were alive when the clothes rubbed than 100% hemp fiber. Shinayakasa, a texture that feels when a garment that does not feel soft, smooth or resilient is rubbed, is measured. It is measured that 1 to 4 and 9 to 12 of the specimens are softer, softer, and smoother than 100% hemp fiber. .

Tensile strength and elongation were measured to measure the durability characteristics of the teaching materials according to the present invention. Tensile strength was as shown in Table 6.

As shown in Table 6, in the case of 5 to 8 test pieces in which the polyester was used for the warp, the tensile strength value was higher than 100% of hemp, and 1 to 4 using rayon and 9 to 12 using the modal in the test pieces. In the case of test specimen of, the tensile strength value was very low. However, the tensile strength of the weft yarn was low in 3, 7, and 11, while the other strength of the weft yarn was not much reduced compared to 100% of the other specimens.

As a result of measuring the elongation for measuring the durable characteristics of the teaching fabric according to the present invention, the elongation showed the results as shown in Table 7.

Elongation of each test piece (Unit:%) standard One 2 3 4 5 6 7 8 9 10 11 12 slope 1.76 4.63 3.67 4.45 4.70 4.93 4.88 4.63 5.16 4.36 4.33 4.23 4.57 Weft 3.55 1.38 3.10 3.88 4.60 4.22 4.31 6.44 5.44 1.23 1.23 3.65 5.08

As shown in Table 7, the elongation in the weft direction of each specimen showed the same or slight increase, and the elongation in the warp direction was significantly increased compared to 100% of the hemp.

In order to measure the comfort of the teaching material according to the present invention was measured for absorbency and warmth. Since absorbency is a hygienic performance that is closely related to the absorption of sweat secreted from the eye, summer clothing should have good absorbency. Absorbency measurement results were as shown in Table 8.

Absorbency of each test piece standard One 2 3 4 5 6 7 8 9 10 11 12 slope 27.6 49.5 47.9 64.2 37.5 23.9 24.4 27.2 32.2 40.5 45.8 58.2 38.4 Weft 29.9 32.7 31.1 36.2 29.8 16.6 16.7 19.4 22.5 29.5 29.6 36.1 27.8

As shown in Table 8, in the case of the test specimens of 1 to 4 using rayon and 9 to 12 using modal for the warp, the absorbency was higher than that of 100%.

The result of measuring the thermal insulation for measuring the comfort of the teaching material according to the present invention showed the results as shown in Table 9.

Thermal insulation of each test piece (Unit:%) standard One 2 3 4 5 6 7 8 9 10 11 12 Warmth 21.9 14.4 5.7 24.9 18.8 32.3 24.3 27.3 29.9 17.7 29.6 18.6 14.6

Referring to Table 9, in the case of 5 to 8 in which polyester was used for warp among the test pieces, the thermal insulation showed a higher value than 100%, and in the case of 1 to 4 and 9 to 12, in which rayon and modal were used. The results showed that the value of warmth was very low. It is judged that artificial fibers using ramp rayon and modal do not impair the anti-defense effect of hemp fibers, making it suitable for summer clothing.

As a result, the teaching fabric according to the present invention has a drape property 40-80% increased compared to 100% hemp fiber, elongation is increased 6-70%, fusitivity 30-80% increased characteristics superior to 100% hemp fiber Indicated.
